Stefanie Powers will replace Harper on tour. The Bushnell date is rescheduled to May 7 to 12. The tour will now kick off in Florida.

Powers was in the 1965 film, "Die, Die, My Darling" with Bankhead, the very film Bankhead is "looping" in "Looped."

Harper was nominated for a Tony Award in 2010 when she played outspoken actress Tallulalh Bankhead in “Looped” on Broadway in the three-actor play. Rob Ruggiero directed that production and is staging the tour as well.

Harper, an Emmy Award winning actress best known for her role as Rhoda in “The Mary Tyler Moore Show” and the spinoff series, “Rhoda,” is home in Santa Monica receiving medical attention. The specific nature of her illness is not yet disclosed.

Harper was also promoting her memoir, “I, Rhoda,” which was released in stores earlier this month. In the boiok, Harper talks for the first time her bout with lung cancer.
